Visible crew/equipment: When Clarence Boddicker (Kurtwood Smith) is killed by Murphy (Peter Weller), Boddicker falls into the steel mill's water, blood spewing from his neck. Sharp eyes are required here to see that there is someone standing against the wall in the background... (01:32:40)
Visible crew/equipment: Robocop tries to arrest Dick Jones but fails, and an ED-209 is brought in to destroy Robocop. During their fight scene, it fires a missile at Robocop, and you can see the guide wire that the missile flies along (slo-mo helps but it's not necessary). (01:09:00)
Visible crew/equipment: In the scene where all the OCP executives are listening to Dick Jones presenting ED-209, and while the "old man" starts talking about Delta City, watch when the camera moves along backwards to show the city model he's talking about and you can see reflected on several TV sets that are on the wall both the camera operator and another man behind him, perhaps the boom operator. (00:09:25)
Visible crew/equipment: When Clarence is racing away from Lewis near the end of the movie, the camera zooms in on Clarence driving the car and the camera men and camera truck are visible in the reflection of the car. (01:29:35)
Visible crew/equipment: When RoboCop is going to the mayors office to stop Miller you can see the camera shadow on the reporters, just after he gets out of the car, and on the police lieutenant when he asks him "What the hell do you think you are doing?". (00:36:58)
Visible crew/equipment: When Robocop tries to arrest Dick Jones, Robocop's system messes up. In the close shot of Robocop's helmet the whole film crew is visible. (01:10:10)
Visible crew/equipment: When RoboCop enters the rave party, you can see the shadow of the camera twice, once on dancers, the other on a wall with a neon light picture on it. (00:55:25)
Visible crew/equipment: When Robocop is riding in his patrol car just before the "Mom and pop" store robbery, if you watch closely as the camera is behind the cage in the car. You can see a camera man's silhouette in the lower right corner enjoying the ride. (00:33:45)
Visible crew/equipment: Just before Clarence Boddicker crashes his SUX into the water, the camera view zooms down to the driver's window. If you look in the paintwork below the drivers window, you can see the camera and operator being reflected. (01:29:35)
Visible crew/equipment: Robocop shows up at city hall and is hounded by reporters. We see his point of view. The shadow on the bottom left is that of the camera filming the shot. It noticeably has a shade so light doesn't reflect into the lens and is visible at least twice.
Visible crew/equipment: Before he collides with Lewis, when the camera goes in close to Clarence driving you can see the camera crew and equipment reflected on the door.
Visible crew/equipment: As Robocop first drives out into the city, there is somebody's head in the extreme right side of the frame, even though he's alone in the car.
Visible crew/equipment: As Robocop walks through the abandoned house, his memories of what it used to look like come into play. The gold vases in his memory reflect the camera crew and equipment.
Visible crew/equipment: Right after Clarence Boddiker blows off Murphy's hand with a shotgun, Murphy turns around grasping his wrist and begins to face the four criminals that are about to kill him. During this scene of him turning around, you can see a crew members fingers move in the bottom right corner of the frame. We know it's not Boddiker's fingers, as he was just wearing black gloves when he shot off Murphy's hand. (00:22:35)
Answer: Because he knew he was doing illegal activities. Robocop was said to be highly efficient at his job and Jones did not want to risk him out on the streets without the insurance of shutting him down if Robo came after him.
